## Abstract A procedure for numerical quadrature over a semi‐infinite range is described which does not require storing weights or nodes. It is applicable to a wide variety of integrands including oscillatory functions and forms with integrable singularites. A computer program and numerical example
Gauss quadrature rules corresponding to weight functions (1 + x2) -" on the interval (0,~x~) have been proposed R.E Sagar, V.H. Smith Jr. and A.M. Simas, Comput. Phys. Commun. 62 (1991) 16) for the evaluation of atomic momentum expectation values. In this comment it is shown that by using Gauss-Rati
